In an all time high, the KSE 100-share index gained 402.25 points to hit 31,332 points.
Financial analysts said that the KSE index moving past the 31,000 points mark was a very positive sign for the economy.
Earlier on November 5, the benchmark KSE index of 100 shares closed at 30,593 points, while throughout last week the KSE index has shown gains due to increased trading of shares.
The previous peak of 30,474 points had come in July, but the exchange plunged in August after the protests and sit-ins by opposition leaders Imran Khan and cleric Allama Tahirul Qadri in Islamabad.
